AUGUSTE LEON PUCEL, OF SCEAUX, FRANCE.

WARNING APPARATUS FOR THE PROTECTION OF VALUABLE OBJECTS.

To all whom it mag concern:

Be it known that I, AUGUSTE LEON PUoEL, a citizen of the Republic of France, residing at 58 Rue Voltaire, Sceaux, Seine, in the Republic of France, engineer, have invented certain new and useful Improvements in lVarning Apparatus for the Protect-ion of Valuable Objects, of which the following is a specification.

This invention relates to improvements in warning apparatus for the purpose of protecting valuable objects, such as pictures, strong-boxes and the like, by giving an alarm signal as soon as an attempt is made to remove, perforate or damage such objects.

The object of the invention is to provide means whereby to prevent the circuits necessary for connecting the divers-valuable objects with the signaling device from being cut or rendered useless otherwise. To accomplish this it is indispensable that all the circuits, together with the batteries, the signaling device and all the connections shall be protected without any solution of con tinuity. For such purpose the said circuits are inclosed in a wrapper closed at every part and which comprises narrow parts in.

the shape of sheaths inclosing the conductors and enlarged parts in the shape of casings large enough to inclose the batteries, the signaling devices and the like, and such wrapper is encircled at every part by a metal jacket which acts on spring switches mounted in the said wrapper in such a manner that such jacket or even any part thereof cannot be removed without such switches operating and closing a signaling circuit.

Several embodiments of this invention are shown by way of examples in the accompanying drawings, in which Figure l is a transversal section of a wrapper in the shape of a sheath with the metal jacket. Fig. 2 shows in elevation the details of such wrapper. Fig. 3 is a transversal section of a wrapper, showing a switch actuated by a connecting screw. Fig. 4 represents two current-taking devices adapted to engage each other. Fig. 5 is a diagram partly in section and partly in elevation of an apparatus so fitted as to protect two pictures. Fig. 6 is a horizontal section on the line AA of Fig. 5, of a casing inclosing the batteries and the signaling devices. Fig. 7 is a cross section on the line Specification of Letters Patent.

BB of Fig. 5, of a part of the wrapper. Fig. 8 is a fragmentary elevation of a wall of the said Wrapper, seen from within. Fig. 9 is a fragmentary longitudinal section of such wall. Fig. 10 is a detail section of the wrapper at the point junction of a lateral branch. Fig. 11 shows partly in section and partly in elevation a picture, seen from the rear. Fig. 12 is a vertical section on the line .C-C of Fig. 11. Fig. 13 is a detail section of a wrapper comprising two series of spring switches. Fig. 14 is a fragmentary longitudinal section of a modified wrapper.

' In Figs. 1 and 2, a designates a wooden conduit designed to inclose the wires of the electric circuit to be protected. On the four faces of such conduit are secured, by screws or studs, hollow beads or boxes, 6, b b 5 which inclose the switches serving to protect the wrapper. These parts as a whole are surrounded by a metal casing composed of sheet iron plates 0, 0 c 0 assembled together by bolts 0, 0 The switches located in the beads b, b 5 may be of any suitable kind adapted to be held normally open as long as the metal casing remains closed, and to close automatically the corresponding circuits as soon as the parts of the casing are separated. Three kinds of switches are shown in Fig. 1. In the bead b the switch consists of a resilient blade (Z, one end al of which is fixed and the other end (Z tends to apply itself against a contact (Z but is normally kept separated bya wire 6 attached at one end to the said blade and at the other end to one of the bolts 0 of the casing; if the said bolt is unscrewed the wire is released and the blade (Z bears against the contact (Z thus bringing in communication two conductor blades d and (l5 which extend the whole length of the bead and which are connected respectively (see Fig. 2) with the two poles of a circuit comprising a battery and a signaling device, such as a ringing device or the like. The bead incloses switches similar to the previous ones. Within the bead b the switch shown comprises also a blade d and a contact al connected respectively with the blades (Z (Z but the blade (Z is kept separated from the contact d by a push button 6 secured to the top 0 of the metal casing,

so that if the top is raised, the push button I 6 will allow the blade (Z to rise and close the circuit on the contact (Z In the bead I) is located a switch comprising a rod (Z slidable in the guides d and subjected to the they may be so near together as to render.

italmost impossible to. insert a. boring tool inthe wrapper without encountering one of the switches; if allthe blades (Z. are connected with the same pole ofthe circuit and if the metal casing is in communication with the other. pole the boring tool will then close the circuitin. touching both the metal casing and one of the blades (Z, so that.

the attempttobore will be signaled. For the'same purpose, the inner wall ofthe parts of the metal casing may be lined with several coatings, of conducting materials separated by layers of insulating materials, preferably in uniting intimately the said layers together, and with the metal casing so that they cannot be separatedand fur thermore in makingthem very thinso that a tool boring the casing willnot tail to reach one of the innerconducting coatings; the latterbeing connected with one pole of a, circuit of a warning circuit and the metal casing with the other pole, the alarm will thus be given .as soon as the tool has pierced the said casing.

More particularly, the sheet metal may be covered by an insulatingvarnish and such varnish may be baked up to between 200 and: 300 degrees centigrade, and then a coating of metallic powder. may be spread on, the said varnish, a suitable binding material being added to such powder, the

whole being baked again. There may be also applied on the varnish coating one or more thin metal sheets, of tin for instance, with the contingent intercalation of sheets of paper 01-, of other. insulating.

material, the whole being united by means of varnish or other binding material.

The wrapper a will generally be composed of pieces of wood assembled together by means of screws or studs to form'sheaths, boxes or the likerectangular in. cross section. There maybe added to the above described protecting means, a supplementary protecting means consisting of switches placed within the wrapperand actuated direct by the said screws, studs or other fasteningv members, forinstance as shown in Fig. 3, where the fastening, screw f, uniting two walls a and a ..of the wrapper, acts by its point against a resilient blade 03 to separate the same froma contact when screwed home, such blade and such contact, being secured to the wall a andcOnnected with the two poles of a warningcircuit. If an attempt is made to loosen the screw f, the blade (Z is released andcomes and bears against the contact (Z in closing the circuit.

The wrapperv a will generally be of such a length as to require to be composed of several parts assembled end to end. It will. the'n'b'e suitable to insure the connection of the corresponding portions of the circuits inclosed in such parts by means of simple and safe connections. One embodiment-of such connection is shown in Fig. 4:, where an insulating support g, secured withinone of the parts to be assembled, carries two metal blades 9 g mounted on its opposite sides and bearing yieldingly against an intermediate blade of insulating material j secured also to the support gfthe blades 9 g are connected by the wires 9 g with the terminals of the switches carried by the walls of the said part of the wrapper. In the other part. to be assembled, an insulating support it is also secured :and carries two re silient blades [i 7LT, which are connected-by wires fi 71 with the terminals of the switches mounted in the said part of the wrapper;

g g in forming a closed nozzle. Such engagement takes place when the two parts are brought together to be assembled, so that the wires 71. are then connected with the wires g 9 If the. two parts of the wrapper are separated, the blades b 7& make contact again with one another and put in communication the wires it II In practice, each end of the fractional part of the wrapper will be provided with a pair of blades 9 9" and with a pair of blades 71}, ]L2 and similar pairs of-blades will be arranged symmetrically in diagonal at the opposite end so that the said fractional parts can be indiiierently turned end for end. W hen the two consecutive parts of the wrapper are separated, there will be a closure of the warning circuit by the blades it 71, of thatpart which remains connected with the poles of the warning circuit.

Fig. 5 shows diagrammatically an apparatus composed of fractional parts of the wrapper thusconstructed and assembled and so fitted as to protect two pictures 5 2' The w apper .comprises .a box a inclosing two batteries and is, two ringing devices j and 7.2 and a notice-board having eyepieces j serving to indicate the numbers of the pictures which might be removed or damaged. The inner walls of such box are provided with spring switches (Z (Z of the by sheet-metal plates 0, c c c 0, 0 which cover all the faces of the said box and such switches closing automatically in case such plates should be separated from the walls of the box. In the front wall is provided a door a (see Fig. 6) also provided with switches (Z (Z and with a sheet-metal plate a such wall carries the switches (Z (Z arranged to be opened by push-buttons o-r projections (2 associated with the door when the said dOOr is open. All the blades (Z and the contacts (Z are connected respectively with the two poles Z0 and Z0 of the circuit comprising the battery is and the ringing device so that neither the door can be opened nor one of the sheet-metal plates forming the metal casin of the box a be removed without the ringing device Zc being set in motion.

Besides the box a", the wrapper comprises a sheath (6 which extends from such box to the pictures to be protected and which is constructed in a similar manner to that of the box; such sheath is fixed to the walls and may comprise of course elbows as at m (see Fig. 5), one or several branches as at 012), and even parts widened in the shape of casings as at m or of boxes similar to the box a The details of such sheath are shown in Figs. 7 to 10. It is composed of parts or sections tubular in cross section which are provided with metal casings 0, c 0 c of the above described kind and with spring switches (Z (Z all the poles of such switches are connected respectively to the poles Z62 and k through the medium of wires g and if, h secured within the sections and pairs of blades 9 and M, if placed at the points of junction, so that the ringing device will operate as soon as one of the sheet-metal plates will have been removed or one of the sections will have been separated from the others.

All the parts of the metal casing c are lined with conductor sheet a, of tin for instance, which are insulated from the sheetmetal by insulating coatings of varnish 0 and of paper 0 Such metal sheets 0 and such tin sheets a are connected respectively with the poles of the switches (Z (Z so that the ringing device 70 will operate also when the said sheets 0 and a will be put in communication by any kind of boring tool. Sheets of paper 0 are gummed to the inner face of the tin sheets n to prevent them from being damaged by the heads of the push buttons 6 for the same purpose the heads of such buttons are provided-with wide and flat plates 6 Furthermore, it will be ad vantageous to insure the electric communication of the successive metal sheets 0 by overlapping their edges from which the varnish has been taken off as shown in Fig. 9, and also the communication of the successive tin sheets a bymeans of strips of tin n forming bridges above the joints and making contact with the sheets n across the openings provided in the sheet-s 0 Each of the casings m located behind the pictures to be protected (see Figs. 11 and 12) incloses a series of spring switches (Z, (Z similar to those represented in Figs. 1 and 2, which are held open by the tension of the tapes e attached at one end to the blades (Z and at the other end to the beads 79 inserted between the canvas and the frame 2' of the picture, so that should one of such tapes be cut, the blade (Z released would bear against the contact (Z Contacts (Z are located in front of the contacts (Z so that if a greater pull is made on the tapes 6, the blades will bear against the contacts All the blades (Z on the one hand and all the contacts (Z (Zl on the other hand are connected with the poles and j* of the circuit comprising the battery 7', the ringing device y' and one of the magnets of the notice board 7' through the medium of insulated conductor wires 0, so that when any one of the blades (Z will touch one of the contacts (Z or (Z*, the said circuit will be closed and the ringing device j will operate and at the same time the board 7' will indicate the number of the corresponding picture Z 7 The tapes 6 are placed directly againstthe back of the canvas of the picture and are allotted in a sufficient number on the whole of the surface so that one of the same at least will be reached when the canvas is lacerated or otherwise damaged by a spiteful hand. To secure the casing m and to guide the tapes behind the picture without modifying either the frame i or the frame-work Z of the latter, a supplementary frame 7* will be preferably used and which will be firmly secured to the frame a and will carry the casing m}, as well as a suitable number of cross pieces T the latter serving to support pulmeans of a metal jacket or outer casing and of switches kept open by the pressure of such outer casing; but such protecting members have not been shown for greater clearness in the drawings.

The picture 2' is protected in the same manner as the picture 6 through the medium of wires (j, 9 connected with the pole 7' and the pole 7' of the second electro-magnctof the board 7' there may be any number of pictures or other objects to be protected.

Fig. 13 shows a part of a warning apparatus adapted to protect a valuable object. The latter is placed direct on a box or casing m inclosing switches arranged on its upper It will be understood that and lower walls; those at, (Z are opened by the, weight of the object t, theweight of which holds the pusher members a lowered and slidable through openings of the upper wall;those (Z, (Z? are opened by. the pullon the wires passing also through the openings of such wall and attached-(to the socle of the object 6'. All the blades being connected with one pole of the warning circuit and allthe contacts being connected with the other pole, the said circuit would surely be closed as soon as the object is removed or as the wires 61 will have been cut. The late :11 walls of the casing at will be protected in the same manner as those of the wrapper represented in Figs. 5 to 10.

Fig. 1 L shows a modified construction of the protected wrapper, wherein the wall a for instance is provided outwardly with a series ofjuxtaposed rectangular plates u, (2 a, 6 The plates unare secured to the said wall a and the plates 6 are associated with the movable pusher members 6 which serve to separatethe blades d from the contacts (Z all such plates are connected electrically with the blades tl and hence with a pole of the warning circuit, while the metal casing c of the wrapper is connected with the other pole. coating of varnish or other insulating. mate rial 0 and the plates a, c are also covered with a. coating-of insulating material 0 so that when thecasing bears against the said plates the warning circuit isopened; ita hole is bored through the casing 0, the tool will surely encounter one of the plates 10 or e and close the circuit; it will be the same if the casing c is broken out, for one at least of the plates 0 will be released and will allow of the corresponding switch being closed.

It must be understood that the alarm sig nals may be of any suitable kind; instead of ringing devices there may be employed for instance electric detonators or the like.
